TO ALL WHOM IT MAY CNGERN:

ne it known um I, WILLIAM HARTLEY Mime, of Philadelphia, in nl@ county of Philadelphia, and Seite of Pennsylvania, have invented n new and improved Method of Applying Oil, Liquid Grease, or Wax, to Packing for Stuing-Boxes of Engines and Pumps; end I hereby declare that the following is a. full, clenr, and exact i description thereof', reference being had to the accompanying drawings, melting part of. this specification,

The nature of my invention consists in the' use of oil,` liquid grease, orV wax, in combination with dry powdered and dry fibrous material, by a process which secures the said powdered and fibrous material from the effects of water or condensed steam. l p l To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and mode of operation.

A and B, in the drawings, represent sections of the ordinary combinetionmof dry powdered with dry ibrous material, in the usual form of packing-rope, after having been saturated with oil, melted grease, or wax, in the manner and for the purpose herein more specifically set forth. i

Having the fibrous materiel spun into yarn or thread, I spool the yarn, and place it in a spool-rack. The spools,l rrrck, and spooling-machine used are an exact counterpart of machinery and applinncesus'cd in cotton.- mills for putting yarn upon spools for weaving, warping, or other purposes.

Having placed a tanker other reservoir within a few yards of the' spool-rack, or creel, (as yit is sometimes called,) I fill the reservoir with dry powdered substancevto about one-half the capacity of the said reservoir; and, in order to `'secure the combination of' this dry powder with the dry fibrous threads es they are united in rope, by being led from the spool-rack into the reservoir, and thence to a twisting-nmmratus, I nowmld to the dry powder n; lubricating-oil, liquid grease, or wax, using steam-heating apparatus to melt and keep the compound warm. It is necessary that the wax should be kept nearly up to the boiling-point, thus securing athorough mixing of.the powder, fibre, and oil, grease, or wax, und rendering t-lle combination secure from the effects of water in. pumps, lund condensed steam in "steam-stuug-boxcs. i

In some instances, I prefer a process somewhat as follows, viz: Having the rope formed of dry powdered and dry fibrousV materiel partially secured by u cover, after the mxlnner shown in the patent of J. B. Miller and Vil. H. Miller, dated-April 4, 1865, I ll the reservoir above alluded to with oil, grease, or wax, or a, combination of oil and wax,or of oil 'and water, and, having the lubrieantboiling hot, I immerse the shove-described dry rope in the reservoir, which process unites the fibre, powder, and oil. p

Eitllerof the above processes secures the combination of wnx or oil through the entire body of the rope;

and this oil, wax, or grease prevents the water' from washing out the powder, and hence adds greatly to the security of the joint. i

What I claim as my invention, and desire to secure by Letters Patent, is- The process above described, or its substantiel equivalent, whereby the combination of dry powdered and dry'tibrous materiel may be secured from the effects of water or condensed steam.
